The purge of government employees that have scientific expertise continues. On Friday, the last three members of the White House’s Office of Science and Technology Policy (OSTP) closed the door to their office for the final time. “Science division out. Mic drop,” one of the employees tweeted.

All three staff members were holdovers from the Obama administration. Under his leadership, the OSTP had nine employees that were the executive branch’s brain trust on issues like STEM education, biotechnology, and crisis response. According to CBS News, there is no one working in that division of the OSTP now and no clear indication that replacements will be chosen.
